TLDR
CT fluoroscopy-guided NAB of pulmonary lesions provides high diagnostic accuracy and can be performed with significantly fewer complications, however, radiation exposure to both patient and doctor were significantly higher than conventional CT- guided NAB.Abstract:
We evaluated radiation doses, complication rates, and diagnostic accuracy for CT-guided percutaneous needle aspiration biopsy (NAB) procedures of pulmonary lesions performed with or without fluoroscopic guidance. A total of 142 patients were prospectively enrolled to receive CT-guided NAB with (Group I, n = 72) or without (Group II, n = 70) fluoroscopic guidance. Outcome measurements were patient and doctor radiation dose, and complication rate. Sensitivity, specificity and accuracy were calculated based on 123 NAB results. The mean estimated effective patient radiation dose was 6.53 mSv in Group I and 2.72 mSv in Group II (p 0.05). CT fluoroscopy-guided NAB of pulmonary lesions provides high diagnostic accuracy and can be performed with significantly fewer complications. However, radiation exposure to both patient and doctor were significantly higher than conventional CT-guided NAB.read more

C-Arm Cone-Beam CT-guided Percutaneous Transthoracic Needle Biopsy of Lung Nodules: Clinical Experience in 1108 Patients
TL;DR: Cone-beam CT-guided PTNB is a highly accurate and safe technique with which to diagnose pulmonary lesions with reasonable radiation exposure and virtual guidance was a significant protective factor for both pneumothorax and hemoptysis.

TL;DR: Pneumothorax frequently occurred and placement of a chest tube was occasionally required for pneumoth orax after CT fluoroscopy-guided lung biopsy, and physicians should adopt the shortest needle path to the lesion to reduce the risk of pneumothOrax necessitating chest tube placement.

Risk of pneumothorax in CT-guided transthoracic needle aspiration biopsy of the lung.
TL;DR: Increased lesion depth and smaller lesion size correlated strongly with the development of pneumothorax and chest tube placement related to the severity of the patient's obstructive lung disease.

TL;DR: Use of CT guidance considerably expands the scope of thoracic lesions amenable to percutaneous biopsy, and the high rate of pneumothorax, its treatment, and advantages of its immediate radiologic management are discussed.

TL;DR: Lesion size was a determining factor in diagnostic accuracy in CT-guided automated needle biopsies of lung nodules and decreased in proportion to the decrease in the lesion diameter.

TL;DR: Although CT fluoroscopy is a useful targeting technique, significant radiation exposures may result and radiologists need to be aware of different methods of CT fluoroscopic guidance and the factors that contribute to radiation exposure.
